short 6.5mm
Norma used to make a target/training bullet at 80 grains. I've got a bunch of them from shooters clearing their shelves and some in factory Norma ammo. The factory stuff shoots accurately at 100m and was cheaper than factory brass. Might find some of those bullets lurking around if that is a small enough bullet (and they are quite short, and round nosed and full patch).
